ESP12E Serial Com via USB-Port

Hi Guys, again, just starting with the ESP12E Module, upload via OnBoard USB Port (USB-Serial CH340).
I did serial.swap() after serial.begin(baud) to map RX and TX to D8/D7 and communicate via an FTDI-Chip.
Is there a way to use the Programming-Port to communicate via the OnBoard USB directly without using the ftdi?

OK, solved it myself by chance, I´ve been using VisualStudio, where Dtr and Rts mode on the serial Port are being enabled by default. Hovering the mouse over the respective Button shows like: "Some boards like the ESP8266 have a setting to turn off Rts since they won´t work if it´s on"
Doing so and all works well!
